Great news for makers of kitless pens or custom pens.
Triple start threads, or triple lead threads are popular amongst pen makers because it means the pen cap can be removed or replaced with fewer turns. Whereas, depending on the length of your thread, it takes several turns of the cap to screw it on with a single start thread, a triple start thread will do it in a couple of turns or less and is far more professional that way.
They’re not cheap, but there again they are not poor quality throw away items either. Made specially for us from M2 HSS steel by TapCo, the globally acclaimed precision thread cutting specialists, they are available as a set comprising a split die paired with an intermediate (second) tap, which with care and proper use will last a lifetime.
Currently available in 10 x 0.8 and 12 x 0.8, the range will be expanding over the coming weeks and months to include six sizes from 10mm up to 14 mm
